In this paper, we describe the dynamics of a vector-borne relapsing disease, such as tick-borne relapsing fever, using the methods of compartmental models. After some motivation and model descriptionâ€¦ (More)

It was recently shown that the nonlinear logistic type ODE with periodic harvesting has a bifurcation on the periodic solutions with respect to the parameter : uâ€² = f(u)âˆ’ h(t). Namely, there existsâ€¦ (More)

The Sherman-Woodbury-Morrison (SWM) formula gives an explicit formula for the inverse perturbation of a matrix in terms of the inverse of the original matrix and the perturbation. This formula isâ€¦ (More)

We have investigated the structures of U(V1) oxides precipitated from room temperature aqueous solutions at low ionic strength as a function of pH. Using the uranium LIJJ edge extended x-rayâ€¦ (More)
